ZOSI C220 review

Four 8 MP cameras at 20 frames per second with AI person and vehicle classification and two-way audio at each camera, in IP66 housings. ZOSI states 30 m (98 ft) night vision and plug-and-play PoE wiring.

The conclusion A well-specified mid-priced kit whose audio is the unusual part. Budget for a hard drive: none is supplied.

This kit sits at the low end of the wired hub on price, without a drive, and its distinguishing feature is not the sensor: it is that every camera has a microphone and a speaker.

Why audio at the camera changes the system

A wired system is normally something you review after the fact. Two-way audio makes it something you act with — telling a delivery driver where to leave a parcel, answering somebody at a side gate, or making it plain to a person in a yard that they are being watched by a person rather than by a recording.

In this hub, the ieGeek IE92 and the Loocam LC8P8B state it too; the other three kits do not.

The specification, honestly read

8 MP at 20 frames a second, which is smooth for any security purpose. AI classification of people and vehicles, which on a wired system saves your attention rather than power — it decides whether the morning’s notifications are worth opening.

IP66 housings, stated by ZOSI for rain, snow and temperature extremes.

The drive, bought separately

ZOSI states the hard drive is sold separately: the recorder takes a 3.5-inch SATA drive. It decides how many days of history you keep, and it is a cost to add, where the other kits in this hub supply a 1 or 2 TB drive. The recorder offers continuous, motion and scheduled recording, with detection zones and notifications, and the ZOSI app gives access from a phone, tablet or PC.

Who it suits

A house where the system should be used rather than only consulted.

Availability

What reassures, and what does not

Strengths

  • Two-way audio at the cameras, not just at a doorbell
  • AI person and vehicle classification cuts the notification volume
  • IP66 housings stated for rain, snow and extremes
  • Plug-and-play PoE: one cable per camera

Compromises

  • 20 fps rather than 25 or 30 — smooth enough, but stated and worth knowing
  • Hard drive sold separately, where the other kits in this hub supply one
  • A recorder must be sited somewhere ventilated and powered
  • Cabling remains the real installation cost

The questions we are asked

Does 20 fps matter?

Rarely. Twenty frames a second is smooth enough for any security purpose, and the difference against 25 is invisible in normal viewing. It becomes relevant only when you pause on a single frame of something moving fast, where a higher rate gives more frames to choose from.

What is two-way audio at a camera for?

Speaking to somebody standing in front of it — a delivery driver, a caller at a side gate, somebody where they should not be. It is the feature that separates a system you watch from a system you use, and half the kits in this hub do not state it.

Is the AI classification worth having on a wired system?

More than on a battery one, oddly. A wired camera records regardless, so the classification is not saving power; it is saving your attention. It decides whether the notification list is worth opening in the morning.
